Abstract
Provided are an aircraft control method and a rotorcraft. The method comprises: acquiring a current angle of attack of a lift-enhancing wing (60) by means of an angle-of-attack sensor (70); according to the current attack angle and a set angle relationship, calculating a target included angle between the lift-enhancing wing and a rotor wing (50), the set angle relationship being an association relationship between the included angle, between the lift-enhancing wing and the rotor wing, and the attack angle; by means of an angle adjuster, adjusting the included angle between the lift-enhancing wing and the rotor wing of the rotorcraft to be a target included angle; and when the included angle between the lift-enhancing wing and the rotor wing is the target included angle, correspondingly adjusting an angle of attack of the lift-enhancing wing to be an optimal angle of attack. The control method achieves the optimal lift-drag ratio working condition of lift-enhancing wings, reduces the power consumption of rotor wings, and improves the load capacity, the endurance time and the endurance mileage of rotorcrafts.
